CUTTER-PIN.

Beit knownthat I, FRANK EDWARD Hirn, ,al .c1t1zenof thel United States, residing et Owensboro, 1n the county of useful Improvements in Split or Co iter i;ins, of which the following is a speciticetion.

This invention relates toacotter in of the' l split type, and reletes more particu arly to o.

means whereby the s ring members or arms of the pincan be he d in compressed posi-K tion so as to facilitate the insertion of the pin in the part intended to receive the same.

. The invention has for one of its objects to provide' a comparatively simple, inexpensive and durable form of-eotter pm having spring arms vnormally sprung outwardly, in conn-ection with e. coller or equivalent means shdebl'y arranged on the )in wherebythe arms een be held compresse to render the insertion of the pma comparatively simple matter, end also possessing the advantage of dispensin lwith the bend-ing of the arms of the pin an the subsequent straightening thereof, should.

it be desired to use the pin again after re- Vin Figi -will t us be seen thet the extremities o f the movel. i A- furtherobject of the invention is the prov1s1on of a cotter pin having the entrcmiN tiesof itsspring arms-bulged oppositely so that the compressing collar can be retained between the eye of the pin andthe bulged extremities'.` a' y With these objects in :View rnd others, as

- will appear as the description proceeds, the

invehtioncomprises the various novel feau tures of `construction end arrangement of parts which will be more fully described here- A luefter-(andv setvforthv with perticulerity .in i the claims appended hereto.

bolt, and 2, e nut, the bolt being with an opening for the'reception ot the cot ter pin designated by 3. The cottcr pin is constructed of spring wire end bent toi'ormprovided en eye i end spring arms 5 that normally spread elpert, the extremities of the4 arms being bu ged. oppositely, as at 6. Disposed on the arms 5 and retained thereon between the eye, 1i and bulgod extremities 6 is e compressuig ineens 7 in the form oi' a collar hevf ing oprositcly disposed lugs 8 for permitting 4 the ce ler `to be conveniently gripped between the ngers. By menus of this coller,

the spring arms 5 can be com ressed ini wardly toward each other to te position shown 'in iiig. 3, whereby the bulgedextremities ofv the pin can be readily entered in the hole of the bolt 1. After the pin is entered, the longitudinal pressure applied. to the ege or hea. 4 causes the pin to pass into t e lo onine to its fullextent, the collar 7 sliding. l

e ong the arms as the pin is inserted. Since the arms 5 have e. normal'outwerd tension, their extremities will spring -epart es shown 1, when the pin is fully inserted. It

arms do not beve to be s` rung apart as 1s or dineriljtY re 'uired, end t at when the pin .is 1 removed, t 1e arms will compress together, v

tive and that such changes maybe made when desiredJ es are within the'soope ofthe' claims. n A

Having 'thus described theinvention, what I claim is 1. Acotter in having armstending to.

spring outward and a collar slideble on the arms for compressin them together, said with outwardly ex'- tending lugs forming gripping means.

2. A cotter pin comprising en eye and @es of the construction and spring urns their eXtIx member slid n the arms to eompress the same sind peri ently retained between the eye and bent portions of the arms,

3. A Cotter p in comprising an eye and sFring arms normally spread apart, a collar s dably monted on the pin for compressing the arms, and means coperating with the \FRANK EDWARD HITE. Viitnesses.: 'i
